Atoms in a Magnetic Field: Quantum Mechanical Treatment,The ordinary Zeeman effect is a beautiful example of the fact that even with classical physics, one can obtain results similar to those of strict quantum theory. In order to set our earlier results on a firm basis, however, we shall now go through the strict quantum theoretical treatment.绑架 发表于 2025-3-27 03:07:40

Many-Electron Atoms,The simplest many-electron atom is the helium atom. In the ground state, its two . electrons exactly fill the innermost shell with the principal quantum number . = 1. There is no room for more electrons in this shell, as we shall see below.令人心醉 发表于 2025-3-27 11:35:11
